Question

Which equation could be used to solve problems involving the relationships between the angles?

Responses

A (12 + a) + (7a + 12) = 90(12 + a) + (7a + 12) = 90

B 90 + (12 + a) = (7a + 12)90 + (12 + a) = (7a + 12)

C (12 + a) − (7a + 12) = 90(12 + a) − (7a + 12) = 90

D (7a + 12) − 90 = (12 + a)(7a + 12) − 90 = (12 + a)

E (7a + 12) + 90 = (12 + a)
